The release of Oct. 10. is still, under OSX 10.6, incompatible with Parallels Desktop 4. When I start my Virtual Machine, Parallels Desktop reports it is unable to access the Hard drive. Apparently, NTFS-3G does not release control of the Bootcamp-partition to parallels. This was no problem with the last free build and OSX 10.5.8.2. Somehow, it is also not possible to access my Macintosh via SMB-Protocol from a Windows machine. Though ping is working, shared folders do not appear under Windows. Both problems were solved by uninstalling NTFS-3G - a hard one, for even the old driver was otherwise working fine under 10.6.1.
